Title: Improvements in the manufacture and production of low boiling hydrocarbon products
Filed: 1928-10-13
Abstract: 328,618. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 13, 1928. Hydrogenation,destructive; hydrocarbons, cracking. - Carbonaceous materials which are liquid at room temperatures are converted into hydrocarbons of low boiling point by treating them with a stream of hydrogen or hydrogenating gases at elevated temperatures and pressures so that products richer in hydrogen are obtained and then subjecting these products to a cracking treatment in the presence or not of reducing gases such as hydrogen, nitrogen, carbon-monoxide or dioxide. A high partial pressure of hydrogen is preferable in the first stage and catalysts immune from poisoning by sulphur may be employed e.g. elements of the 6th group together with those of groups 2-4, the treatment being relatively more strenuous than that described in Specification 296,429 for the elimination of sulphur. The temperatures specified in the first range from 300- 550‹ C. and the pressures from 5-200 atmospheres or over while the temperature in the second stage may be raised to 700‹ C. and splitting catalysts employed so that aromatic products are largely obtained, or the conditions may be arranged that largely unsaturated gaseous hydrocarbons are obtained. Catalysts specified for the first stage include those prepared from oxides of molybdenum, zinc, magnesium, tungsten, aluminium and thorium, Florida earth, kaolin, chromic acid, nickel sulphide, while those used in the second stage include bauxite, kaolin, Florida earth, silica. luntonite, zinc oxide, manganese dioxide, silica, calcium aluminate, oils shale residues, anhydrous halides of metals and solid metalloids such as aluminium chloride, ferric chloride, boron fluoride &c. A viscous producer tar containing 30 per cent of a fraction boiling up to 350‹ C. is treated in the liquid form with a stream of hydrogen at 430- 450‹ C. and 200 atmospheres in the presence of a catalyst prepared from the oxides of molybdenum, zinc, and magnesium. The product obtained contains 10-15 per cent of a fraction boiling up to 200‹ C. and 70 per cent of a fraction boiling at 200-350‹ C. These products are subjected to a cracking treatment and a product containing 50-60 per cent of a motor fuel is obtained. In a further example the cracking is carried out at 480‹ C. and 200 atmospheres pressure in the presence of molybdic acid. zinc oxide and magnesia, and a non knocking benzine rich in aromatic compounds is obtained. In another example a tar containing aromatic hydrocarbons is hydrogena.ted at 430‹ C. and 200 atmospheres in the presence of molybdenum and chromium and the product is cracked at 550-600<‹> C. and 200 atmospheres in the presence of calcium oxide and iron. A fraction boiling below 200‹ C. is obtained and also a gas containing 30-50 per cent of olefines and diolefines. Specifications 221,559, 239,556, 249,156, 257,912, 268,774, and 272,194 also are referred to. Reference has been directed by the Comptroller to Specification 272,194.

Abstract: 746,276. Tubular heat exchangers. BABCOCK & WILCOX, Ltd. Dec. 19, 1952 [Dec. 22, 1951], No. 30078/51. Class 64(1). The external surfaces of a bank of horizontal or inclined heat exchanger tubes are cleaned by causing the gases, which normally have an upward or downward flow, to flow transversely of the tubes laterally within the tube bank. In the drawings the reference 2a indicates one only of four vertically spaced tube banks of an air heater associated with a tubulous vapour generating and superheating unit. Above the unit are three dampers 12a, 12b, 12c, Fig. 2a, and below are three dampers 13a, 13b, 13c. These dampers each consists of a plurality of spaced tubes which normally are clear of the tube bank, as in the case of the damper 13a, Fig. 3, so as to permit the downflow of the gases, but which can be moved to close the spaces between the adjacent row of the tube bank as in the case of the dampers 13b, 13c. Actuation of the dampers is effected by fingers 22 which extend radially from rotatably mounted shafts 24a, 24b, 24c and 24a<SP>1</SP>, 24b<SP>1</SP>, 24c<SP>1</SP>, arranged as shown, the fingers projecting into the ends of the damper tubes. Rotation of the shafts is effected by handles 46a, 46b, 46c, and 46a<SP>1</SP>, 46b<SP>1</SP>, 46c<SP>1</SP>, associated with holding devices, Fig. 6 (not shown). In use, the normal downflow of gases can be temporarily interrupted as shown in Fig. 2a by moving the dampers 12b, 12c, 13a, 13b to the closed position, thus causing the gases to flow laterally over the tube bank as illustrated and freeing them from dust. The gases may then be made to pass in the reverse direction by closing the dampers 12a, 13c and opening dampers 12c, 13a. Specification 746,335 is referred to.

Abstract: 1400913 Milk proteins PATENT TECHNOLOGY Inc 26 June 1973 [21 July 1972] 30365/73 Heading C3H [Also in Division C2] A process for removing protein from non-fat milk containing both whey protein and casein involves heating the milk while at a pH of 6À4- 6À8 to a temperature of 190-200‹ F., dispersing calcium chloride as a precipitant into the heated milk and holding the material for a sufficient period at that temperature to effect precipitation of whey protein, thereafter acidifying the material to pH 5À2-5À4 and holding the acidified material to effect precipitation of casein and formation of a curd, the precipitated whey protein being physically consolidated with the casein during precipitation and curd formation, and then removing the consolidated precipitates from the remaining deproteinized whey. The precipitates are then washed with water, milled, treated with alkali and spraydried. The deproteinized whey is centrifuged to remove curd fines and then concentrated to crystallize and separate the lactose. The amount of calcium chloride used for the precipitation is preferably 0À1 lb. per 100 lb. of milk for a holding period of about 20 minutes. The whey resulting from a conventional separation of casein curd from non-fat milk using rennet or acid may be heated, adjusted to pH 4À2-5À2 and then treated with a flocculating agent such as carrageenin to bring down whey protein. This may be used to supplement the whey protein precipitated as described above.
